Remains of wapiti and bison are reported from a Holocene (9630 ± 300 years BP, and 9670 ± 160 years BP) deposit at Three Hills, Alberta. The wapiti, although slightly larger, is assignable to the extant Cervus elaphus nelsoni. The bison is conspecific with the extinct Bison occidentalis. Detailed morphologic comparisons are made with extant and extinct species of both.
